Two U.S. F16 fighter jets escorted a Panama-City bound plane back to Toronto on Friday after a passenger threatened the aircraft.

Flight 772 turned around over West Virginia about 45 minutes after its 7 a.m. (1100 GMT) departure from Toronto Pearson International Airport, said Sunwing Airlines spokeswoman Janine Chapman. She said an “agitated passenger directly threatened the aircraft” but did not elaborate on the threat.

NORAD Captain Jennifer Stadnyk said the two fighter jets from Ohio flew with the plane out of U.S. airspace as a “precaution.”

Toronto police said Ali Shahi, 25, has been charged with uttering threats and endangering the safety of an aircraft. Police Const. Lilly Fitzpatrick said he’s Canadian.
